Who is responsible for this application?

Application holder is not the same as manufacturer

FDA application holder

Kadmon Pharmaceuticals LLC

The Orange Book identifies this organization as the applicant responsible for NDA 214783.

Manufacturer status

Not established by the Orange Book

A product-specific FDA label or NDC source must independently identify a manufacturer, labeler, distributor, packager, repackager, or relabeler. The applicant name is not used as a substitute for that evidence.

Regulatory interpretation

What the record means, and what it does not
FDA marketing status

1 presentation listed as prescription

RX and OTC are Orange Book marketing categories, not real-time inventory signals. Confirm current commercial availability with labeling, the application holder, or an authoritative drug listing.

Therapeutic equivalence

No TE code is posted for this application

No TE code does not mean FDA found the product ineffective or non-equivalent. FDA generally publishes TE evaluations for multisource prescription products; single-source and some other products may have no code.

Patent & exclusivity record

5 listed patent expirations and 1 exclusivity date remain on or after Jul 26, 2026

The latest future date recorded across those files is Jul 14, 2042. Patent and FDA exclusivity operate independently, can overlap, and do not by themselves predict a generic launch date.

Same-ingredient landscape

0 other ANDAs and 0 other NDAs found

0 of the related ANDA applications are not marked discontinued. Sharing an ingredient does not establish pharmaceutical or therapeutic equivalence; strength, dosage form, route, and TE group still matter.

Which products are meaningfully comparable?

Exact ingredient + dosage form + route cohorts

NDA 214783 appears in 1 comparison cohort. These groups narrow the same-ingredient landscape, but strength and TE code must still match before interpreting therapeutic equivalence.

Why are clinical sections unavailable?

Exact application-label matching status
Exact source match queuedQueue NDA-214783

No exact application-level FDA or DailyMed label match has been reviewed for this application. Approved uses, dosing, warnings, adverse reactions, and clinical evidence remain unavailable rather than being inherited from a related brand, generic, or ingredient record.

Until an exact application match passes human review, this page intentionally omits approved uses, dosing, warnings, adverse reactions, mechanism, and clinical-study summaries. It never inherits those claims from an RLD, brand, generic, or same-ingredient product.

How to use this record responsibly

Scope, limitations, and primary sources

What to verify before making a decision

  • The applicant is the holder of legal responsibility for the application; the Orange Book does not establish that the applicant manufactured or currently markets every listed product.
  • RX, OTC, and discontinued are FDA listing categories, not real-time pharmacy inventory or commercial-availability data.
  • Therapeutic equivalence applies only within the matching ingredient, dosage form, route, strength, and TE-code group; same ingredient alone is insufficient.
  • Listed patent and exclusivity dates are regulatory intelligence, not legal advice, a freedom-to-operate analysis, or a reliable generic-launch forecast.
  • The Orange Book is not prescribing information and does not provide indications, dosing, contraindications, adverse reactions, recalls, or current safety communications.

Official FDA references

Data shown here is normalized for search and comparison. When a regulatory, substitution, launch, or legal decision turns on a field, verify it against the current FDA record and the relevant source document.
